[MITgcm-devel] testreports broken on SunOS

[Martin Losch]

Hi there,
I noticed that testreport doesn't run on Sun anymore since the changes 
on Jan25 (Revision 1.62). The critical line is:
       if (relerr > 0.0) { linnum = (int)log10(relerr); }
was replaced by
       if (relerr > 0.0) { linnum = (int)lrint(log10(relerr)); }

Now I get an error message about lrint:
> model::verification> ./testreport -of 
> ../tools/build_options/sunos_sun4u_f77+mpi_sunfire

what does this lrint do and why do we need it now?
